dask.dataframe.utils.make_meta

dask.dataframe.utils.make_meta(x, index=None, parent_meta=None)[source]

This method creates meta-data based on the type of x, and parent_meta if supplied.

Parameters
xObject of any type.

Object to construct meta-data from.

indexIndex, optional

Any index to use in the metadata. This is a pass-through parameter to dispatches registered.

parent_metaObject, default None

If x is of arbitrary types and thus Dask cannot determine which back-end to be used to generate the meta-data for this object type, in which case parent_meta will be used to determine which back-end to select and dispatch to. To use utilize this parameter make_meta_obj has be dispatched. If parent_meta is None, a pandas DataFrame is used for parent_meta that chooses pandas as the backend.

Returns
A valid meta-data
